Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission
Laser &Photonics Reviews, EarlyView.This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Frozen Differential Scattering in Reconfigurable Complex Media
Laser &Photonics Reviews, EarlyView.A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping
Laser &Photonics Reviews, EarlyView.A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

Filtering harmonic and chaotic signals in non-linear radio electronic systems
Физика волновых процессов и радиотехнические системы, 2018 Creation of non-linear radio engineering systems is the perspective direction. In radio engineering system as informational chaotic fluctuation is used. In work non-linear filtration of mix of chaotic fluctuation and noise is investigated. The non-linear

Dynamic Evolution and Transformative Trends in the Consumer Market: A Technology Paradox Perspective
Psychology &Marketing, EarlyView.ABSTRACT The consumer market is defined by tensions arising from the clash between technological advancement and consumer psychology. Current research lacks a unifying framework to explain these contradictions. Addressing this gap, we introduce a conceptual model based on technology paradox theory, which maps the dynamic process from antecedents ...

Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances
Mass Spectrometry Reviews, EarlyView.Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics
